It's been cold and snowy. A few days ago I popped the trunk but couldn't open it because it was frozen shut.
2-3 days later after the thaw I noticed the the trunk was open. Newish battery is completely dead. Is this normal? I figure at most there is a light in the trunk but I didn't think that alone would drain it so quickly.

I have the battery on a small trickle charger and it's been 2 days and not complete. It is enough to start the car. Is it better for battery health to continue using the trickle charger or reinstall the battery and drive/charge on it.

Thanks for your input!

I would:
Put the battery back in and start the car.
Then drive it around for 30 minutes. Your alternator will charge it better than any trickle charger.
Then I would pop the trunk and give the weatherstrip a wipe-down with WD-40 or baby oil or something, so it doesn't happen again.
Also, do the door weatherstrip for for the same reason.

What is this "thaw" of which you speak??

Haha I live in Vancouver, BC so we got about 3-4 inches of snow and slightly below zero (celsius) for a few days which is enough to shut down the city and cause widespread panic.

I should clarify the trickle charge is a Noco Genius trickle/maintainer. But I'll put it back and start driving on it. Thanks!

Battery can freeze if below 32F and discharged. Put it inside the house and let it warm up before trying to charge it / put it back in the car.
